M/A-COM‘s MAATCC0013 is an integrated voltage
variable attenuator containing two PIN diodes and a
passive glass quadrature hybrid. This device is
packaged in a 5 leaded SOT plastic surface mount
package. Maximum attenuation is typically achieved
at 3.5 V bias using the suggested bias circuit. The
MAATCC0013 is ideally suited for GSM communica-
tion applications requiring variable attenuation in the
824 to 960 MHz bandwidth.
